All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Hamilton Spring-Loaded AEZFHS Heavy Service Casters w/ Duralast Polyurethane Wheels · Up to 1,200 lb

Diameter: 4, 5 inTread: 2 inCapacity: up to 1,200 lb
This collection gathers plate-mount casters used on warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 4, 5 in, polyurethane treads, and capacities 1,200 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
